if the coolant looks fresh, would not bother to drain, but first find out
from where the coolant went, if it was burned through a leaking head
gasket, it's not going to heal itself, but if it is a leaking hose, hoses will
get sloppy and loose with time, in which case you're going to want to
drain the coolant at the lower petcock to replace the lower hose and
while you're at it the upper hose and the cooling/heating hoses too,
okay yes, drain the coolant, but use that down time to affect the
rubber replacement~

if its gone into the engine head gasket replacement easy way to find out remove oil filler cap look on the underside of it if its white like mayonnaise water contaminated oil hopefully for you that its not the case and just a leaky radiator or hose
